ProProgram/Family Table Issue

[TCARPENTER1]

I have a small automation app that creates assemblies based on user input. I have family tables (sort of) they have instance names but nothing else in them (no values etc). I use ProProgram to control the features of the parts I want to suppress or resume instead of the family table, but use the family table to create different instances. The program works fine except for a small glitch. If I call any instance other than the generic, I get a window titled: Information Window (errors.lst) with this in it:

Errors in My models MUNTIN_A1_GT_M.PRT
---------------------------------------
!*** ERR: parent 48244 of feat 48260 missing or suppressed
...
..

It only happens on this one part, which is a simple assembly, only two parts and no duplicates, what am I doing wrong?

TIA
